摘要:
The present invention relates to a piston rod assembly for a drug delivery device, comprising: a piston rod (200) adapted to be operably engaged with a piston (155) of a cartridge (153) containing a medicament, at least one adjusting member (202) displaceably disposed at the piston rod (200) with respect to the piston rod's (200) long axis, and being interconnected with a distal end section (206) of the piston rod (200), and - at least one interlock means (216) adapted to interact with the adjusting member (202) and/or with the piston rod (200) for mutually locking in position the adjusting member (202) and the piston rod (200) in an arbitrary relative position in order to compensate for tolerances of manufacture and/or of assembly.
